Sickle cell disease with left ventricular non-compaction: A rare association.

J Cardiol Cases 2011 Apr 12;3(2):e75-e77. Epub 2011 Jan 12.

Department of Cardiology, Royal Hospital, Muscat, Oman.

Cardiac abnormalities described in sickle cell disease are pulmonary hypertension, dilated left or right atrium/ventricle, valvular abnormalities, hyperdynamic left ventricle with hypertrophy, and left or right ventriclular dysfunction. However, features consistent with left ventricular non-compaction have not been described previously in patients with sickle cell disease. We describe the case of a 21-year-old male with sickle cell disease and left ventricular non-compaction, which is a rare association and discuss the possible mechanisms for such an association.

Classic pseudoxanthoma elasticum in a girl with sickle cell disease.

Pediatr Dermatol 2018 Dec 9. Epub 2018 Dec 9.

Department of Dermatology and Pediatrics, Texas Children's Hospital, Baylor College of Medicine, Houston, Texas.

A pseudoxanthoma elasticum (PXE)-like phenotype develops in a subset of patients with inherited hemoglobinopathies. Although PXE tissue changes are thought to develop in the absence of ABCC6 mutations in patients with beta-thalassemia, ABCC6 mutations have not been well evaluated among sickle cell disease patients with PXE-like disease. To our knowledge, we describe the first patient with sickle cell disease, PXE skin findings, and two confirmed pathogenic ABCC6 mutations. Read More

The sickle cell trait affects contact dynamics and endothelial cell activation in -infected erythrocytes.

Commun Biol 2018 30;1:211. Epub 2018 Nov 30.

1Department of Infectious Diseases, Parasitology, Universitätsklinikum Heidelberg, Im Neuenheimer Feld 324, 69120 Heidelberg, Germany.

Sickle cell trait, a common hereditary blood disorder, protects carriers from severe disease in infections with the human malaria parasite . Protection is associated with a reduced capacity of parasitized erythrocytes to cytoadhere to the microvascular endothelium and cause vaso-occlusive events. However, the underpinning cellular and biomechanical processes are only partly understood and the impact on endothelial cell activation is unclear. Read More

Pre-clinical Development of a Lentiviral Vector Expressing the Anti-sickling βAS3 Globin for Gene Therapy for Sickle Cell Disease.

Mol Ther Methods Clin Dev 2018 Dec 1;11:167-179. Epub 2018 Nov 1.

Department of Life Sciences, University of Modena and Reggio Emilia, Modena, Italy.

Sickle cell disease (SCD) is caused by a mutation (E6V) in the hemoglobin (Hb) β-chain that induces polymerization of Hb tetramers, red blood cell deformation, ischemia, anemia, and multiple organ damage. Gene therapy is a potential alternative to human leukocyte antigen (HLA)-matched allogeneic hematopoietic stem cell transplantation, available to a minority of patients. We developed a lentiviral vector expressing a β-globin carrying three anti-sickling mutations (T87Q, G16D, and E22A) inhibiting axial and lateral contacts in the HbS polymer, under the control of the β-globin promoter and a reduced version of the β-globin locus-control region.

Microvasculature-on-a-chip for the long-term study of endothelial barrier dysfunction and microvascular obstruction in disease.

Nat Biomed Eng 2018 23;2:453-463. Epub 2018 Apr 23.

Wallace H. Coulter Department of Biomedical Engineering, Georgia Institute of Technology and Emory University, Atlanta, GA, USA.

Alterations in the mechanical properties of erythrocytes occurring in inflammatory and hematologic disorders such as sickle cell disease (SCD) and malaria often lead to increased endothelial permeability, haemolysis, and microvascular obstruction. However, the associations among these pathological phenomena remain unknown. Here, we report a perfusable, endothelialized microvasculature-on-a-chip featuring an interpenetrating-polymer-network hydrogel that recapitulates the stiffness of blood-vessel intima, basement membrane self-deposition and self-healing endothelial barrier function for longer than 1 month.

Thrombospondin-1 and Vitamin D in Children With Sickle Cell Anemia.

J Pediatr Hematol Oncol 2018 Dec 4. Epub 2018 Dec 4.

Department of Pediatrics, Faculty of Medicine, Kuwait University, Kuwait.

Background: Thrombospondin-1 (TSP-1) and 25-hydroxyvitamin D (25-OHD) play significant roles in the pathogenesis of sickle cell anemia (SCA). TSP-1 enhances cellular adhesion/inflammation, hence contributing to vaso-occlusive crisis (VOC); vitamin D, in contrast, retards inflammation and may lower rate of pain episodes. We determined serum levels of TSP-1 and 25-OHD in Nigerian children with SCA and their matched hemoglobin AA controls; and assess the relationship between the 2 biomarkers. Read More

Robust adaptive immune response against infection marked by low parasitemia in a murine model of sickle cell disease.

Blood Adv 2018 Dec;2(23):3462-3478

Laboratory of Complement Biology and.

The intraerythrocytic parasite is the number 1 cause of transfusion-transmitted infection and can induce serious, often life-threatening complications in immunocompromised individuals including transfusion-dependent patients with sickle cell disease (SCD). Despite the existence of strong long-lasting immunological protection against a second infection in mouse models, little is known about the cell types or the kinetics of protective adaptive immunity mounted following infection, especially in infection-prone SCD that are thought to have an impaired immune system. Here, we show, using a mouse infection model, that infected wild-type (WT) mice mount a very strong adaptive immune response, characterized by (1) coordinated induction of a robust germinal center (GC) reaction; (2) development of follicular helper T (T) cells that comprise ∼30% of splenic CD4 T cells at peak expansion by 10 days postinfection; and (3) high levels of effector T-cell cytokines, including interleukin 21 and interferon γ, with an increase in the secretion of antigen (Ag)-specific antibodies (Abs).

White Paper: Pathways to Progress in Newborn Screening for Sickle Cell Disease in Sub-Saharan Africa.

J Trop Dis Public Health 2018 10;6(2):260. Epub 2018 Jul 10.

Department of Public Health Sciences, Loyola University Chicago Stritch School of Medicine, Maywood, IL, USA.

Sickle Cell Disease (SCD) is among the most common single-gene diseases in the world but evidence-based comprehensive health care has not been implemented where the highest prevalence of SCD occurs, in sub-Saharan Africa (SSA). It represents an urgent health burden, both in terms of mortality and morbidity with an estimated mortality of 8-16% in children under 5 years in SSA. Addressing the high mortality of SCD in SSA and for effective management of SCD, newborn screening (NBS) should be incorporated with prevention of infections (including pneumococcal septicaemia and malaria), parental education and support at all levels of healthcare provision to enable timely recognition.

New insights into the pathophysiology and development of novel therapies for sickle cell disease.

Hematology Am Soc Hematol Educ Program 2018 Nov;2018(1):493-506

Children's Hospital, Montefiore Medical Center, Bronx, NY; and.

Although the seminal event in sickle cell disease is the polymerization of abnormal hemoglobin, the downstream pathophysiology of vasoocclusion results from heterotypic interactions between the altered, adhesive sickle cell red blood cells, neutrophils, endothelium, and platelets. Ischemia reperfusion injury, hemolysis, and oxidant damage all contribute to heightened inflammation and activation of the hemostatic system. These various pathways are the focus of emerging treatments with potential to ameliorate disease manifestations. Read More

Therapeutic strategies for sickle cell disease: towards a multi-agent approach.

Nat Rev Drug Discov 2018 Dec 4. Epub 2018 Dec 4.

Division of Hematology, Oncology and Transplantation, Department of Medicine, University of Minnesota, Minneapolis, MN, USA.

For over 100 years, clinicians and scientists have been unravelling the consequences of the A to T substitution in the β-globin gene that produces haemoglobin S, which leads to the systemic manifestations of sickle cell disease (SCD), including vaso-occlusion, anaemia, haemolysis, organ injury and pain. However, despite growing understanding of the mechanisms of haemoglobin S polymerization and its effects on red blood cells, only two therapies for SCD - hydroxyurea and L-glutamine - are approved by the US Food and Drug Administration. Moreover, these treatment options do not fully address the manifestations of SCD, which arise from a complex network of interdependent pathophysiological processes. Read More
